Asphalt-basedcured carbon feltand graphite felt
1) productdescription
This product ismade of bituminous carbonfiber felt by steel compound treatment, the producthas certain rigidity,self_supporting, small specific gravity, no short fibershedding, excellent heatinsulation efficiency. The products are widely used inall kinds of atmospherefurnaces, heat treatment furnaces, single crystalsilicon draw furnaces, polysiliconingot furnaces, etc., especially for ceramicsintering furnace and siliconcarbide recrystallization furnace withtemperature above 2200 ℃.
Can provide flatplate, disc, cylinder andother shapes, long service life easy to install anddismantle.
